Funny how this conversation started how crypto is slow and expensive, and now turned into slow and expensive is OK :P. In a crypto world, you don't need to convert to Euros. Are we in a crypto world yet? No. Will we live in crypto world in the future? Maybe, when it's faster and cheaper ;).

All "common transactions" use credit (even when you use a debit card). The banks approve transactions quickly, but reconcile those transactions slowly.
